[0039] Example 1:
[0040] Please see Figure 1-8A multifunctional plastic mold with self-testing function includes a plastic mold assembly 1. The plastic mold assembly 1 includes a fixing frame 11. A lower mold 12 is fixedly installed on the bottom of the inner wall of the fixing frame 11. An electric telescopic rod 13 is fixedly connected to the top of the fixing frame 11. An upper mold 14 is fixedly connected to the output end of the electric telescopic rod 13. Both the upper mold 14 and the lower mold 12 have mold grooves inside. Both the upper mold 14 and the lower mold 12 have viewing windows on their exteriors. The viewing windows facilitate subsequent testing work by the staff. An air extractor 2 is fixedly installed on one side of the fixing frame 11. The air extractor 2 is powered by an external power source and is used to extract air from the interior of the upper mold 14 and the lower mold 12. The air extraction pipe on the air extractor 2 is connected to one end of the top of the upper mold 14, and the other end of the top of the upper mold 14 is connected to an injection molding pipe 3. The upper mold 14 is a transparent acrylic sheet. This configuration not only facilitates the user's subsequent observation of the equipment's testing status but also allows the user to observe the entire working process, making it convenient to use. One end of the injection tube 3 is connected to the injection molding machine. Both the lower mold 12 and the upper mold 14 are equipped with multi-functional self-detection components 4. These components can be used for vacuum testing in the early stage of mold making and for applying release oil to the mold. There are multiple sets of these multi-functional self-detection components 4, which are evenly distributed around the mold grooves inside the upper mold 14 and the lower mold 12. This arrangement allows users to easily check the air content inside the mold raw materials in the upper mold 14 and the lower mold 12. This arrangement can improve the overall product quality of the equipment and facilitate its use. The multifunctional self-detection component 4 includes an inner groove 41. A rectangular frame electromagnetic block 42 is fixedly connected to the bottom of the inner wall of the inner groove 41. Multiple connecting springs 43 are fixedly connected to the inner side of the rectangular frame electromagnetic block 42. A magnetic plate 44 is fixedly connected to one end of each of the multiple connecting springs 43. A detection cylinder 45 is fixedly connected to one side of the magnetic plate 44. A detection reactant placement groove 46 is opened inside the detection cylinder 45. The detection reactant placement groove 46 is filled with a reactant, which is a substance that can react with oxygen in the air and produce a significant color change. The reactant can be a very active metallic element or other substances that are extremely easy to react with oxygen to produce other substances. There will be a significant color change during the reaction. With this setting, it is convenient for staff to see in time and take corresponding countermeasures.
[0041] The lower mold 12 has multiple expansion grooves connected to the interior of the inner groove 41.
[0042] Multiple expansion slots are arranged in a linear array at equal intervals.
[0043] An air inlet 47 is connected to the inside of the detection cylinder 45 and the outside of the detection reactant placement tank 46. A waterproof and breathable mesh is provided at the connection between the detection reactant placement tank 46 and the air inlet 47. By providing a waterproof and breathable mesh, the release oil can be prevented from entering the detection reactant placement tank 46 when the user applies the release oil.
[0044] Inside the detection cylinder 45 and at the top of the reaction material placement tank 46, there is a release oil connecting tank 48. The top of the detection cylinder 45 is threadedly connected to a nozzle 49. The nozzle 49 and the detection cylinder 45 are detachably connected. This design allows for easy replacement by the staff and facilitates use. The nozzle 49 is a conical nozzle. A silicone protective plate 410 is fixedly installed at the liquid outlet of the nozzle 49. The silicone protective plate 410 has a cross-shaped liquid outlet groove inside. When the silicone protective plate 410 is not in use, the cross-shaped liquid outlet groove is in a closed state. When the silicone protective plate 410 is in use, the cross-shaped liquid outlet groove is in an open state.
[0045] A liquid supply tank 411 is fixedly connected to one side of the lower mold 12. The liquid supply tank 411 is used to store release oil. The liquid supply tank 411 is provided with a liquid inlet and a sealing plug. This design allows the staff to add liquid in a timely manner. One end of the liquid supply tank 411 is connected to a liquid supply hose 412. A pump body 413 is provided on the liquid supply hose 412. Driven by the pump body 413, the release oil inside the liquid supply tank 411 can be easily applied for subsequent coating work (the pump body 413 is powered by an external power source).
[0046] There are multiple detection cylinders 45, which are arranged in a linear array and equidistantly distributed in the mold groove inside the lower mold 12. The number of detection cylinders 45 is equal to the number of telescopic grooves. The multiple detection cylinders 45 are connected to each other through telescopic hoses 414, and the liquid supply hose 412 is connected to the telescopic hoses 414 through a T-connector.
[0047] The lower mold 12 has side grooves 415 on both sides of the telescopic groove. A support spring 416 is fixedly connected to one side of the inner wall of the side groove 415. A block 417 is fixedly connected to one end of the support spring 416. The block 417 is slidably connected to the inside of the side groove 415. Through the elastic force of the support spring 416, the block 417 can slide well, which makes it convenient for workers to use.
[0048] There are two blocking blocks 417. When the two blocking blocks 417 are closed, they can be used to seal the expansion groove. The blocking blocks 417 make it easy to close the expansion groove, which is beneficial for the staff to carry out subsequent work.
[0049] The rectangular electromagnetic block 42 and the magnetic plate 44 have the same magnetic poles. When the rectangular electromagnetic block 42 is energized, it generates magnetism, at which point the rectangular electromagnetic block 42 and the magnetic plate 44 will repel each other. A control switch is provided on the lower mold 12, and the control switch is electrically connected to the rectangular electromagnetic block 42. The control switch can control the connection or disconnection of the power supply to the rectangular electromagnetic block 42. This is prior art and will not be described in detail here.
[0050] Working Principle: During use, plastic material is input into the lower mold 12 and upper mold 14 via an injection molding machine. After input, the air inside is removed by driving the vacuum pump 2. After removal, the multi-functional self-testing component 4 can be used to perform self-testing on the equipment. During testing, the power supply of the rectangular frame electromagnetic block 42 can be turned on by controlling the switch. Since the rectangular frame electromagnetic block 42 and the magnetic plate 44 have the same magnetic poles, the mutual repulsion between the two can stretch the connecting spring 43. At this time, the blocking block 417 will squeeze the support spring 416 and cause the support spring 416 to undergo elastic deformation. The two blocking blocks 417 will move in opposite directions, making it easy to open the telescopic groove. After opening, multiple detection cylinders 45 can enter the mold grooves of the lower mold 12 and upper mold 14. The reactants inside the multiple detection cylinders 45 react with oxygen in the air. The reaction produces a color change, which the user can directly observe through the upper mold 14. The number of color changes indicates whether the vacuum pump 2 needs to be turned on again. When the number of color changes exceeds the calibrated value, it indicates that there is a lot of air inside. At this time, the air can be expelled by driving the vacuum pump 2. During the detection process, since the nozzle 49 on the detection cylinder 45 is conical, it is easy to puncture the air pores inside the plastic material, making it easy to use. After the detection is completed, it can be reset. Since the present invention has multiple sets of multi-functional self-detection components 4 set around the inside of the lower mold 12 and the upper mold 14, it is convenient to conduct a comprehensive inspection of the plastic material inside the lower mold 12 and the upper mold 14, which helps to ensure that the equipment is in a completely vacuum environment, thereby helping to ensure the subsequent quality of the product and making it easy to use.
[0051] After testing, the user can first turn on the power to the rectangular frame electromagnetic block 42, which will release the testing cylinder 45. Then, the user can drive the pump body 413 to apply the release oil. Driven by the pump body 413, the release oil in the supply tank 411 can be delivered to the release oil connecting groove 48 inside the testing cylinder 45 through the supply hose 412 and the telescopic hose 414. The release oil can be sprayed out through the nozzle 49. With the setting of multiple testing cylinders 45, the release oil can be evenly coated on the plastic material, which will facilitate the subsequent demolding work of the equipment. By adopting mechanized operation, the practicality of the equipment can be greatly improved and it is easy to use.
[0052] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
